- CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 252,197, dated January10, 1882. Application filed November 12, 188k (No model.)

To all whom it may concern Be it known that I, ROBERT H. DOWLING,

' of Newark, in the county of Licking and State of Ohio, have invented anew and Improved Oar-Coupling, of which the following is a full, clear,and exact description.

The object of my invention is to provide a new and improved car-couplingof simpleconstruction, and which can be operated without endangering thelife or limb of the operator.

The invention consists in a draw-head provided with a segmental apertureextending from top to bottom and adapted to receive a segmentalcoupling-pin attached to an arm swinging on a pintle in the center ofthe circle of the segmental aperture, which arm is provided with top andbottom extensions. A guide-frame provided with elongated side loops andcrank handles is loosely mounted on the ends ofthe transverse pintle,and is used to raise and guide the link.

Reference is to be had to the accompanying drawings, forming part ofthis specification,in which similar letters of reference indicatecorresponding parts inboth the figures.

Figure 1 is a longitudinalelevation of two draw-heads provided with myimproved coupling, one of the draw-heads being shown in section on theline 3 3 Fig. 2. Fig. 2 is aplan ot' the same on the line mm, Fig. 1,one of the draw-heads being shown in section.

The draw-head A is provided with a central end recess, B, for the linkB, and is further provided with a slot, 0, in the upper surface, andwith a segmental aperture, D, extending from the top to the bottom ofthe drawhead, the middle of the curve being nearest the end of thedraw-head.

A circularly-bent or segmental coupling-pin, E, is attached to an arm,F, which is loosely mounted on a pintle, G, passing transversely throughthe draw-head on the center line of the circle of which the curvedaperture D is a segment, so that the segmental coupling-pin can swing onthis pintle into this segmental aperture. The arm F is provided with anex tension, H, above the segmental pin E and an extension, J, below'thepintle G. -A rod or thick wire, K, is bent to form a link-guide and tofit around the end of the draw-head loosely. It is provided with twoelongated side loops, L L, one fitting on each end of the pintle G, andtwo end crank-handles, M. The upper or outer extension, H, of the arm Fis attached to a rod, cord, chain, or other device, by means of whichthe arm F and segmental pin E can be raised.

The operation is as follows: If the curved pin E is in the positionshown in the righthand side of Fig. 1, the arm F is swung in thedirection of the arrow, causing the curved pin E to pass through thelink B, previously passed into the end of the draw-head, whereby thislink will beheld as shown in dotted lines in the left-hand side ofFig. 1. If the link is held in one draw-head it only need be guided intothe opposite draw-head, and as soon as itstrikes thelower extension, J,of the arm Fitthrowsthe arm F and the curved pin Eforward in thedirection of the arrow,causing the pin E to pass through the link. Toguide the link I have provided the linkguide K, which generally hangsdown, as shown in Fig. 1, on the righthand side. If the link is to beraised, the linkguide 'is turned on the piutle G by means of one of thecrank-handles M. The elongated loops L permit of moving the link-guideforward or backward, as may be necessary.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. In a car-coupling, the combination of thecoupling-link B and the draw-head A, provided with the central endrecess, B, the slot 0, and the segmental aperture D, extending entirelythrough the draw-head, the arm F, pivoted in the said draw-head andprovided with. the segmenfal coupling pin E, the projection H above thecoupling-pin, and the projection J below its pivot-pin, substantiallyasshown and described, whereby the coupling-pin is adapted to be trippedby the end of the link striking the projection J of the said arm, as setforth.

2. In a car-coupling, the combination, with 'the draw-head A and thepintle G, haying its ends extended on each side of the said drawhead, ofthe swinging guide-frame K, provided with elongated side loops, L, andcrank-handles M, substantially as shown and described, whereby the guideis adapted to be moved forward or backward, as may be necessary, as setforth.
